Three different problems that look the same
A volume problem. More jobs than one person can schedule and route. Real, and it needs capacity.
A routing problem. Enough capacity but the day is built badly — technicians crossing the metro, jobs sequenced without regard to geography, gaps that could have been filled.
An information problem. Dispatch does not know enough to schedule well. Job durations are guesses, technician skills are not recorded, and the first visit frequently turns out to need something nobody brought.
Most businesses assume the first and have one of the other two.
Measure what is actually happening
For two weeks, record:
- Jobs scheduled per day
- Average travel time between jobs
- Wrench time as a share of the working day
- Jobs rescheduled, and why
- Callbacks and second visits
- Time from enquiry to scheduled appointment
Wrench time is the number that matters. If technicians are productive for four hours of an eight-hour day, the problem is not dispatch volume — it is how the day is built.
Fix routing before adding people
Greater Houston's geography punishes bad routing more than most markets. Crossing the metro at the wrong time of day can consume an hour and a half in traffic, and a schedule built without that in mind wastes a technician's afternoon.
What helps:
- Group jobs geographically by day, so each technician works an area rather than the whole region
- Schedule around traffic, not just around clock time
- Build in realistic travel buffers rather than optimistic ones
- Keep a list of flexible jobs that can fill a gap in a specific area
- Give technicians the next job before they finish the current one
Fix the information problem
If dispatch is guessing, no amount of capacity helps:
- Record actual job durations by type, and use the real numbers rather than the estimates
- Record which technicians can do which work, including certifications
- Capture enough on the enquiry call to schedule correctly — equipment type, access, age of the system
- Track which job types routinely need a return visit and schedule them accordingly
A business that stops sending the wrong technician recovers more capacity than it would gain by hiring.
Then, if it is genuinely volume
When the day is well built and information is good and it still does not fit:
- Split dispatch by region or by service line
- Move scheduling of routine and maintenance work out of dispatch entirely
- Add part-time cover for the peak scheduling window, usually first thing
- Consider software that handles routing, if you are still on a whiteboard or a spreadsheet
Watch what breaks first
Under pressure, dispatch stops doing the things that are not urgent: confirming appointments, following up on quotes the technician left, calling customers when running late. Those are the activities that protect revenue and reputation, and they disappear silently.
If they have stopped, that is the evidence that capacity is genuinely short — and it is a better argument than anyone's frustration.
Frequently asked questions
What are the three possible bottlenecks?
Volume — genuinely more jobs than one person can handle; routing — enough capacity but a badly built day; and information — dispatch guessing at durations, skills and requirements. Most businesses assume volume and have one of the others.
What is the most important number to measure?
Wrench time — the share of the working day technicians are actually productive. Four productive hours out of eight means the problem is how the day is built, not dispatch volume.
Why does routing matter so much here?
Greater Houston's geography punishes bad routing. Crossing the metro at the wrong time can consume ninety minutes, so schedules must group jobs geographically and account for traffic, not just clock time.
How do I fix an information problem?
Record actual job durations by type rather than estimates, record which technicians can do which work, capture enough on the enquiry call to schedule correctly, and track which jobs routinely need a return visit.
How do I know capacity is genuinely short?
When the non-urgent work stops — confirming appointments, following up technician-left quotes, calling customers when running late. Those disappearing is better evidence than anyone's frustration.
